Am I Ready for the Illinois Permit Test?
12-question diagnostic · 4 easy, 4 medium, 4 hard · Updated July 12, 2026
Twelve questions, deliberately mixed: four easy, four medium, four of the hardest in our verified Illinois bank. The real test needs 80% — but a diagnostic this short needs a margin, so read your result like this: 11+ of 12, you're ready to book; 9–10, you're close — drill the 25 hardest first; below that, work the full test ladder before test day.
Answer each question to see the explanation. Your score is tallied against the real passing bar at the end.
1. For a driver 21 or older, it is illegal to drive with a blood-alcohol concentration (BAC) of:
Show answer & explanation
Correct answer: 0.08 or more
A driver 21 or older is legally under the influence at a BAC of 0.08 or more. You can still be charged below that if alcohol or drugs impair your driving.
2. Which license do you need to drive an ordinary passenger car in Illinois?
Show answer & explanation
Correct answer: A Class D driver’s license
The Class D license is Illinois’s standard non-commercial license for ordinary passenger vehicles. A Class M license is for motorcycles, and Class A/B/C are commercial (CDL) classes for large trucks and buses.
3. When you park next to a curb on a two-way street, your right-hand wheels must be:
Show answer & explanation
Correct answer: Parallel to and within 12 inches of the curb
On a two-way roadway you must park parallel to the curb with your right-hand wheels within 12 inches of it (or as close as practicable to the right edge of the shoulder).
4. Illinois law requires every motor vehicle driven on public roads to be covered by:
Show answer & explanation
Correct answer: A liability insurance policy
Every vehicle operated in Illinois must be covered by a liability insurance policy meeting the state minimum limits. Proof of insurance must be carried in the vehicle.
5. In a business or residential district, how far before a turn must you signal?
Show answer & explanation
Correct answer: At least the last 100 feet before the turn
In a business or residence district you must signal continuously during the last 100 feet before turning. Outside such districts (higher speeds) the requirement is 200 feet.
6. Outside a business or residential district (on higher-speed roads), how far ahead must you signal a turn?
Show answer & explanation
Correct answer: At least the last 200 feet before the turn
Outside a business or residence district, you must signal continuously for at least the last 200 feet before turning, giving faster traffic more warning.
7. While operating a commercial motor vehicle, a driver is considered under the influence at a BAC of:
Show answer & explanation
Correct answer: 0.04 or more
The limit for a driver operating a commercial motor vehicle is stricter: 0.04 or more BAC, half the 0.08 limit for regular driving.
8. How close to a crosswalk at an intersection may you park?
Show answer & explanation
Correct answer: No closer than 20 feet
You may not stand or park within 20 feet of a crosswalk at an intersection; parking closer blocks the view between drivers and pedestrians.
9. When following a motorcycle, you should:
Show answer & explanation
Correct answer: Allow a larger following distance than you would for a car
Motorcycles can stop quickly and may slow by downshifting without their brake light showing. Leave extra following distance so a sudden slowdown does not catch you out.
10. Driving without insurance and causing bodily harm to another person is:
Show answer & explanation
Correct answer: A separate, more serious offense than simply driving uninsured
Illinois defines "operation of an uninsured motor vehicle causing bodily harm" as its own, more serious offense, with heavier penalties than ordinary uninsured driving.
11. A road is often most slippery:
Show answer & explanation
Correct answer: During the first few minutes of rain after a dry spell
When rain first begins, it mixes with oil and dust on the pavement to form a slick film. That mix is most slippery in the first few minutes, before heavier rain washes it away.
12. Stopping, standing, or parking a vehicle on railroad tracks in Illinois carries:
Show answer & explanation
Correct answer: A mandatory fine of $500 or 50 hours of community service
Illinois law imposes a mandatory $500 fine or 50 hours of community service for stopping, standing, or parking on railroad tracks — a stalled or parked vehicle on the tracks is a deadly hazard.
